Patent DE-19745945-A1 (DE)
Title: Optical sample measurement useful for analytical chemistry and medical diagnosis
Inventor: LEISTNER HERMANN
IPC: G01N21/55
Filed: 1997-10-17
Abstract: Samples in an optical system can be observed for comparatively measuring the sample surface (10) in a reference and test condition illuminated by monochrome and polarized light beams (30) at different strike angles. The intensity of the reflected light (36) is measured for each strike angle, and the sample characteristic is determined from a minimum of the light intensity through a change in the light strike angle. In an Independent claim an apparatus has a light source (14) to direct light beams at the sample surface (10) at various angles. A photodetector (18) registers the intensities of the reflected light for each light strike angle. Preferred Features: The light beam (30) is focused at a focal point before, after or on the sample surface (10), to be reflected and registered simultaneously by a number of spaced photodetectors (18), across the optical axis, for different reflected angles as a diverging reflected light beam (36). The light beam (30) has a linear polarization, and the light is reflected with elliptical polarizing. Or the light (30) at the sample surface has an expanding wedge shape. The calibration measurement is functionally related to the sample characteristic from the minimum light intensity through the light strike angle change, and a comparative measurement of the sample characteristic from the light strike angle change of the minimum intensity as a calibration function value. A correction measurement is made without an analyzer (16) in the reflected light path, and the registered light intensity is weighted with the correction function when the analyzer (16) is in place. The light polarization, the mean light strike angle and/or the light strike range of the transmitted light (30) and/or the oscillating plane of the analyzer (16) and/or the light wavelength are set to give a maximum angle change of the intensity minimum on comparative measurements. The sample material is on a substrate (12) of metal, semiconductor or insulating material, with a receptor layer specific to the sample material. The light is transmitted by a laser (24) at the light source (14), preferably as a semiconductor laser or a light emitting diode, with a focusing lens (32) or cylinder lens. The transmitted light is polarized (26).

Title: Motor vehicle headlamp with multi-zone reflector
Inventor: REISS BENOIT
IPC: F21S8/12
Filed: 1997-10-27
Abstract: A car headlamp has a gas-discharge lamp, a reflector and a smooth or a very lightly deflecting cover disc. The reflector can generate a beam that lies below a bright-dark boundary. At least two cover elements belong to the lamp which define two shaded zones on the reflector.  The reflector includes at least two reflecting zones (11 to 13) which cause the formation of beam components that are located below the predetermined bright-dark boundary with different degrees of scattering width. These zones are separated by generally radial transition planes, of which at least some extend into the shaded zones that are defined by the cover elements.

Patent DE-19751033-A1 (DE)
Inventor: ENGLERT HEINRICH
IPC: B27F1/04
Filed: 1997-11-19
Abstract: For transverse profiling of a workpiece ends (20) the tools (4,5) and the workpiece (1) move relative to each other. The relative movement can be produced either by moving the tool across the fixed workpiece, moving the workpiece relative to the fixed axis of the tools or moving both the tools and workpiece. An Independent claim is made for a grooving machine with a workpiece conveying track (2) and one or more machining tools on the same side a stop bar. The tool (4) on the stop bar side moves transverse to the conveying direction (8) by at least the maximum breadth of the workpiece. After an initial transverse profiling the workpiece can be moved backwards and turned around before moving the tool across the other end face. The workpiece then continues in the conveying direction through the machine. Alternatively the transverse profiling is produced at one end (20), moved further through the machine and stopped while the other end is profiled with the same or a different tool. For milling a profile around a frame assembled from the workpieces the variable position tool is removed and replaced by a different tool or two variable position tools located on one side of the conveying track are used with the frame being rotated through 90 degrees for milling each side.

Title: Appliance and method for controlling operation of vehicle passenger safety device in impacts
Inventor: FUJITA KOICHI
IPC: B60R21/013
Filed: 1997-11-19
Abstract: The appliance has an impact measuring device located at a specific position in the vehicle. An initiation control system (44) compares the level (f(G)) calculated from the measured level of the impact (G) with a threshold level (T). The threshold level varies in accordance with a specific threshold level modification pattern. The initiation control system switches on the passive safety device according to the comparison result.  At a position in front of the impact measuring device (32) there is located an impact detector (30) which determines whether or not the impact is weaker than a specific reference level. If the impact is not weaker than the reference level a threshold level modification pattern changeover appliance changes the specific threshold level modification pattern to another pattern.
